Aand to give strength and' rigidity to such struct-urz. if

In the drawings, like reference-numerals views.

Euch plnteis lient to Yform two separated longitudinal panels l which are connected bv D Y n Y :t centra: panel 2, sind panels l being d1- rected outward from Suid panel 2 and stundingr :it equal obtuse :ingles thereto. Said @panels 1 may have lateral, orterminul,

tlnnges 3'. :is shown in' Figs. 1, 2, 3 and 4, or may he provided with one or more longi- Ytudinzilgrihs. or corrufrations et therein atipicent to their outer et ges, as shown in Fig. said ifi-.ingest or corrngntions constituting holding menus wherebyV interlocking asso- ;rintion is had with the concrete of the structure in which the lates are employed; or smid panels may, ii) :is shown in Fig. 5.

In practice. the reinforcement may con` sist o two .sheet metal members the central panels i' of which are fastened together face to tace. as shown in Figs. l to inclusive. or muy consist lof a greater number of such lut' manner with the lateral panels l of euch member fastened to those of the next adjacent members, :is shown in Fig. i'.

The fastening means muy consist of rivets ."x projected through the ndjncent or coincidsaid panels. the slits out in the panels in forming said tongues being in register and said tongues being forced through :unl together clamped down: thaty is, the. tongue strucltu fron-inne punel is turned lmck upon sai punel vund the opposite tongue is forced through the opening in said panel and is tonluc. when snit] members :tre fitted t0- hers, the openings formed hy' bendinfr the tongues `t; over constitute bonds or 2hond openings adapted tolle filled hy the concrete ofthe ltrut-:ure in which the reinforcement is employ-l` through which openings the ,cont-ret.A on opposite sides is bonded or tied. These openings Y nre provided in nl! the panels euch sheet metal member in the,

members.arranged in :i substantially circu-V -ehnnped down over the first intentioned' `etner either in puits or in greater num-y designate like parts throughoutthe-several i :ihly consistsot' tongues t3 struck up from manner described,l whether the tongues struck up in forming said openings are 1ntended for clamping use or not, the. urpvose being to admit of the bondingof t e con,- creteon opposite sidesof the panelsV through such openings. I

In producing a hollowvpost when buttwo reinforcing members :1re employed, each of the'pnnels 2 is provided wit a central longitudinal outwardly bowed semi-circular rib 8, so that when said plates are secured together 1u the manner lllustrated, a central circular opening extending throughout the structure is formed.

`As. is obviors, the invention is susceptibley jof nmnydilferent variations m form, but those adaptations herein shown and described are deemed preferable on account of their simplicity of construction andbeeause easily formed.

Having thus described` our inifention, what we claim as new, and desire to secure by Letters Patent, is

A reinforcement for concrete posts yformed flanges being relatively disposed toform al-v ternate depressions. and raised portions.
